Measuring Functions and Indices

The SP64 provides absolute and difference measurements for the following colormetric systems. These values can be obtained from any of the nine illuminants with 2° or 10° observer angle: CIE XYZ, CIE Yxy, CIE LAB, Hunter LAB, CIE LCH, CMC and CIE94. Whiteness and Yellowness per ASTM E313-98, Metamerism Index and DIN 6172.

Special JOB and PROJECT Modes

The JOB function is a programmed sequence of specific steps to assist the operator in the color measurement process. Up to six lines of specific instructions per measurement routine can be downloaded from X-Rite software and displayed on the SP64's LCD screen. Multiple color standards can also be collected under an identified PROJECT, a feature that supports corporate color standards programs.

Pass/Fail Mode

The SP64 stores up to 1,024 standards with tolerances for easy pass/fail measurement. A red/green LED indicator and the instrument's LCD display provide visual confirmation of results. A tone also sounds to indicate a fail result and measurement completion.

Switchable Apertures

The internal apertures can be quickly changed with the flip of a switch for 4mm or 8mm measurement areas. The instrument will recognise which aperture is being utilized and automatically adapt calibration data. This allows the operator to change measurement mode quickly and efficiently, depending on the sample size.

The Sphere

The SP64's diffusing sphere is made of Spectralon®, a durable, highly reflective material designed to perform in a rigorous production environment. The diffusing material prevents premature degradation due to the flaking and chipping of the sphere wall material.

Inter-Instrument Agreement

The SP64 has superior inter-instrument agreement - essential in multiple instrument color-control programs. The SP64 offers excellent inter-instrument agreement with X-Rite SP62 Sphere Spectrophotometer. Both input data into X-Rite line of Windows-based color quality assurance and color formulation software.

Opacity, Color Strength and Shade Sorting

The SP64 can measure opacity as well as three color-strength options: chromatic, apparent and tri-stimulus calculations. The SP64 also performs 555 shade sorting. These are important considerations in the color quality control of manufactured products involving plastics, painted or textile materials.

Texture and Gloss Influence

To determine the influence of the specular component , the SP64 allows simultaneous measurement of both specular-included (color) and specular-excluded (appearance).

User-Friendly Ergonomics

A wrist strap and tactile side grips make the instrument easy to hold. Read-outs are large and easy to use. A rechargeable battery pack allows extended operation of the instrument.
